Perfusion quantification using dynamic contrast-enhanced ultrasound: The impact of dynamic range and gain on time–intensity curves
Gauthier, Thomas P.; AVERKIOU, MICHALAKIS A.; Leen, Edward L. S. (2011)The objective of this study was to assess the impact of dynamic range and gain on perfusion quantification using linearized log-compressed data. An indicator-dilution experiment was developed with an in vitro flow phantom ...
